If your Windows 10 PC can't see other computers on the network, it's usually due to network discovery settings, sharing configuration, or service issues. Here's how to fix it step by step.

? 1. Turn On Network Discovery and File Sharing

Windows 10 disables network discovery by default in some cases, especially on public networks.

Steps:

• Press Win I to open Settings .
• Go to Network & Internet > Wi-Fi or Ethernet (depending on connection).
• Click on the network you're connected to.
• Make sure the network profile is set to Private , not Public.
  (Only private networks allow discovery and sharing.)
• Then go to Control Panel > Network and Sharing Center > Change advanced sharing settings .
• Under Private network profile:
  • Turn on Network discovery
  • Turn on File and printer sharing
• Under All Networks :
  • Turn on Turn on sharing so anyone with a user account can read and write files
  • Set Password protected sharing to Off (if all devices are in a trusted environment)

? After changing these, restart your PC or restart the network services.

? 2. Ensure All Computers Are on the Same Network and Workgroup

Even if devices are connected to the same router, they must be in the same workgroup and subnet.

Check workgroup:

• Press Win R , type sysdm.cpl , press Enter.
• Go to the Computer Name tab.
• Look at the Workgroup name (default is usually WORKGROUP ).
• Make sure all computers on the network use the same workgroup.

If needed, click Change to rename the workgroup and restart.

Also ensure all computers are on the same local subnet (eg, 192.168.1.x) — check IP settings under Network and Sharing Center.

? 3. Enable SMB 1.0 (If Older Devices Are Involved)

Some older Windows versions or NAS devices rely on SMBv1, which is disabled by default in newer Windows 10 versions.

?? Note: SMBv1 is outdated and less secure — only enable it if absolutely necessary.

To enable:

• Go to Control Panel > Programs > Turn Windows features on or off
• Check SMB 1.0/CIFS File Sharing Support
  • Include both the client and server components
• Click OK and restart

After enabling, try accessing \\ComputerName or \\IP_Address in File Explorer.

? 4. Start Required Services Manually

Some background services must be running for network browsing.

Press Win R , type services.msc , and ensure these services are Running and set to Automatic :

• Function Discovery Resource Publication
• SSDP Discovery
• UPnP Device Host
• Computer Browser (if available — deprecated in newer versions)
• Server
• Workstation

Right-click each > Start (if stopped) > Properties > Set Startup type to Automatic

? 5. Access Computers Directly via IP or Name

Even if computers don't appear in "Network," you may still access them directly.

In File Explorer , type in the address bar:

 \\192.168.1.100

(replace with the actual IP of the other computer)

Or:

 \\ComputerName

The remote PC must have shared folders (right-click folder > Properties > Sharing tab > Share).

? 6. Temporarily Disable Firewall/Antivirus

Sometimes third-party firewalls or antivirus software block network discovery.

• Temporarily disable Windows Defender Firewall or third-party firewall.
• Test if other computers become visible.
• If it works, create exceptions for:
  • File and Printer Sharing (SMB-In)
  • Function Discovery

Re-enable the firewall after testing.

Final Tips

• Restart your router and all computers after making changes.
• Make sure all Windows 10 systems are updated.
• Avoid using Public network profiles for home/office networks.

Basically, the issue is usually just a mix of wrong network profile, disabled discovery, or missing sharing settings. Fix the basics first — set network to Private, turn on sharing, and verify workgroup. Most cases resolve from there.
